Classification and application of hard cutting materials for metal removal with defined cutting edges. Designation of the main groups and groups of application has-tracked-changes Note: BS EN 12271 specifies1 Scope This International Standard specifies the classification and application of hard cutting materials, including hardmetals, ceramics, diamond and boron nitride, for machining by chip removal, and establishes their application. It is not applicable to other uses (mining and other percussion tools, wire drawing dies, tools operating by deformation of the metal and comparator contact tips, etc.).
